This study aimed to develop and evaluate Augmented Reality (AR)-based learning media to enhance students’ cognitive abilities at State Vocational High School (SMK Negeri) 2 Pati, particularly in the subject of Computer Networking and the Internet. The research was motivated by low student achievement in meeting the Minimum Mastery Criteria (KKTP), which was primarily attributed to the continued reliance on traditional teaching methods and low student motivation. A research and development (R&D) approach was employed using the ADDIE model. The resulting AR media is an Android application that integrates text, audio, images, animations, interactive 3D objects, and simulations, and is in accordance with the Merdeka Curriculum. Expert evaluations showed a very high level of feasibility, with ratings of 94% from a subject matter expert and 91% from a media expert. These results were further supported by Aiken’s V index, which indicated very high validity for the material (0.921) and high validity for the media (0.881). A practicality test was conducted, revealing a high level of effectiveness, with a 94% approval rating from both teachers and students. Moreover, a pretest–posttest control group design demonstrated significant progress in learning outcomes. The experimental group achieved an average post-test score of 83.75, significantly higher than the control group’s 73.60. Based on the N-Gain test, the experimental group achieved an average gain of 65.52% (moderately effective), whereas the control group achieved only 38.75% (ineffective). This study contributes to the theories of learning transfer, connectivism, and heutagogy, and offers practical implications for vocational education in adopting innovative technologies. 
 

Teachers are expected to be able to carry out learning in accordance with the merdeka curriculum, including the use of teaching modules in accordance with the provisions of the curriculum. Ideally, teachers can design teaching modules optimally. However, in reality, many teachers are not yet able to create teaching modules merdekaly according to the needs and situations in their learning environment. Several teachers stated that it required additional time, money and energy to compose teaching modules comprehensively, which became an obstacle in preparing teaching modules merdekaly. The Office Management and Business Services Skills Program (MPLB) in Phase F is not included in the Center of Excellence (PK) Vocational School program, part of the merdeka learning program. The aim of this service activity is to strengthen partners' skills in compiling merdeka curriculum teaching modules through several stages: socialization, training, mentoring and evaluation. This devotion was carried out for one week from June 26 to July 3, 2024 offline with 25 teacher participants at State Vocational School 2, Semarang City. The evaluation results show an increase in participants' abilities and skills in compiling Phase F teaching modules according to the existing learning environment.

The high unemployment rate in Indonesia has led many women to choose to work as female migrant workers abroad to overcome their family's economic limitations. This decision not only leads to financial improvements but also brings social changes, especially in childcare. Children abandoned by mothers who work as migrant workers often have difficulty establishing social relationships and receiving adequate emotional support. This study aims to analyze the social behavior of junior high school students in Bawang Sub-district, Batang Regency, who were abandoned by their mothers who work as female migrant workers. The research method used aqualitative approach with a case study through in-depth interviews and observations of children from female migrant workers' families. The results showed that children from female migrant families often have difficulty establishing social relationships due to the lack of direct control and emotional attention from their mothers who work abroad. The study concluded that although the mother's departure helps economically, the challenges in the care and social development of the children were issues that need to be considered. This research contributed to understanding the social impact of the female migrant worker's departure phenomenon on children's behavior.
